Abstract

The invention discloses a method for improving the rubber air tightness, and belongs to the technical field of rubber component manufacturing. The method comprises the steps that additives accounting for 15-20% of the mass of rubber are added in the rubber preparation process, wherein the additives are prepared from, by weight, 15-20 parts of cyanate ester resin, 10-15 parts of acrylic resin, 6-10 parts of sodium tripolyphosphate and 0.1-0.2 part of kaolin. The additives prepared from the cyanate ester resin, the acrylic resin, the sodium tripolyphosphate and the kaolin on the basis of the specific proportion are added into rubber, and therefore the rubber air tightness is improved.

Description

The method improving rubber air tightness
Technical field
The invention belongs to rubber accessory manufacturing technology field, particularly relate to a kind of method improving rubber air tightness.
Background technology
The method improving rubber air tightness is mainly made up of inner glue layer and outer glue-line, and it is applicable to compressed air, automobile parts shop and pneumatic (air pressure) instrument, and water and the conveying of non-corrosive liquid, is widely used in industry, building industry, agricultural etc. and leads.
Summary of the invention
The technical problem to be solved is to provide a kind of method improving rubber air tightness that air-tightness is good.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
It is in the preparation process of rubber, is added into the additive accounting for described rubber quality 15%～20%；Wherein, described additive is counted by weight, is made up of cyanate ester resin 15 parts～20 parts, acrylic resin 10 parts～15 parts, sodium tripolyphosphate 6 parts～10 parts, Kaolin 0.1 part～0.2 part.
Owing to using technique scheme, there is advantages that
The present invention is mainly by adding the additive being made up of cyanate ester resin, acrylic resin, sodium tripolyphosphate, Kaolin of special ratios in rubber, thus improves the air-tightness of rubber.
